To all whom it may concern:

Be it known that I, DUNCAN DUNBAR WRIGHT, aI subject of the King of Great Britain, residing at Arthurette, in the Province of New Brunswick and Dominion of Canada, have invented new and useful Imrovements in Rail-Joints, of which the folowing is a specification.

This invention relates to railroad track construction and more particularly to rail joints of that type in which the abuttingends of the rail sections are designed to overlap and are fastened together in any suitable manner.

The invention has for one of its objects to improve and simplify the construction of devices of this character, so as to produce a strong and durable rail joint, whereby the rails shall be maintained in perfect alinement, sagging prevented and noise and pounding eliminated as the wheels of a train pass over the joint.

A further object of the invention is the provision of a rail joint composed of meetin ends of the adjacent rails which are halve so as to overlap, and the overlapping portions havingone or more projections adapted to engage in openings o the other portion which together with fastening bolts serve to hold the rails securely together and in alinement, there being no necessity for sh plates.

Another object of the invention is to so construct the tread surfaces of the rail sections that the car wheels can ass over the space between the meetin en s of thesections without noise or shoc With these objects in view and others, as will appear as the description proceeds, the invention consists in the various novel features of construction and arrangement of parts, which will be more fully described and .set forth with particularity in the appended claims.

In the accompanying drawing, which illustrates one of the embodiments of the invention :--Figure 1 is a side view of a rail joint. Fig. 2 is a plan view. Fig. 3 is a transverse section on the line 3-3. Figs. 4 and 5 are transverse sections on lines 4 4 and 5-5 of imilar reference characters are employed to designate like characters in the several views.

Referring to the drawing, A and designate the meeting ends of 4two rail sections which latter may be of standard constructionexcept at the meetin ends where they are halved,` so as to over ap. The end of each section is cut away on a center line, as indicated at 1 in Fig. 2,' thereby forming a shoulder 2 and the halved portion of one section is presented to that of the other section so that a substantially uniform rail is produced. On the halved portions 3 and 4 are projections or lugs 5 rojecting laterally' from the central verticalpsurface l, the proection or projections of one section entering an opening or openings 6 of the other section. The overlapping portions 3 and 4 of the rails have transverse bolt receiving apertures 7 for thel bolts 8, whereby the rail sections are secured together. Preferably three bolts are employed at the middle of the rail joint and two at each end.

The tread of each rail section is cut awayat the shoulder 2 and also at the extremity of each halved portion, as indicated by 9, in Fig. l and a portion of the tread opposite the shoulder 2 is raised as indicated at 10, so that the car wheels will pass from one rail section to the other without coming in contact with the meeting end surfaces of the sections. shown in Fig. 1, the extremity of each rail section is provided with a ton ue 11 that engages between the head 12 an base 13 of the adjacent section and these tongues coperate with the rojections 5 to prevent relative vertical disp acement as the car wheels pass from one rail section to the other.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment of the invention'I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as are within the scope of the claims.

I-Iaving thus described the invention, what is claimed, is 1* 1. A rail joint comprising a pair of rails having halved extremities arranged to overlap, projectionsformed integrally with the sald extremities and arranged to engage in openin s in the latter, groups of bolts assing throng the rail sections and dispose at opposite sides of the projections or securing the rail sections together, and tongues proj ecting from the said extremities adapted to pressed portions, and means for connecting 10 engage between and bear on the heads and the rail sections together. bases of the rail sections.
